yes, but what i was referring to was the command line options.  everyone has 
`stat`, but it's really only the GNU stat that supports the '-c fmt' option 
using the semantics necessary here.  `wc -c` is going to work everywhere, but 
i would need to figure out what OS i'm on and where `stat` is coming from so i 
would know how to properly invoke it.
